And now, little children, abide in him, so that when he appears we may have confidence and not shrink from him in shame at his coming. If you know that he is righteous, you may be sure that everyone who practices righteousness has been born of him. 1 John 2:28–29, ESV
There are two types of people in the world. There are God’s children (genuine Christians) and everyone else. One of the reasons I love to read the Gospel of John, 1 John, 2 John, 3 John and Revelation is that John, the disciple whom Jesus loved (John 21:7), wrote very profound words that have no gray areas. Of course he wrote as the Spirit breathed these words through him, but God used this man’s entire makeup in that process. John was very pastoral, but he was also a Christian apologist of the highest order. He was one the three Apostles who made up the inner circle closest to our Lord during His earthly ministry. Before Jesus called him to be his disciple, he was a disciple of John the Baptist along with Andrew, Peter’s brother. Jesus called him and his brother James, the Sons of Thunder. He had great faith, but like most of us, he could get full of himself and focus inward instead of humble and lined up with our Lord’s will alone.
